It is involved in diverse cellular processes, including redox signalling and regulation, xenobiotic detoxification, antibiotic resistance and prodrug activation, among others [ 21 , 125 , [145] , [146] , [147] , [148] , [149] , [150] ]. Upon cellular oxidative stress, MSH protects proteins from oxidative damage through protein mycothiolation, where a mixed disulfide bond is formed between MSH and the protein cysteine thiol (PS-SM).…”
